bug#67758: [PATCH] Add indentation rules for bracketless statements in js-ts-mode

[Noah Peart]

Tags: patch


* Bug: `js-ts-mode` is missing indentation rules for bracketless
statements.

These missing rules are the same as those that were previously missing
from typescript-ts-mode (bug#67031).

Recipe to reproduce:

Using the following function to configure js-ts-mode and indent the
buffer:

    (defun try-indent ()
      (interactive)
      (setq-local indent-tabs-mode nil)
      (setq-local js-indent-level 2)
      (js-ts-mode)
      (indent-region (point-min) (point-max)))

Add the following example to a buffer and call `try-indent`.

    function bracketless_statements(x) {
    if (x == 0)
    console.log("if_statement");
    else if (x == 1)
    console.log("if_statement");
    else
    console.log("else_clause");
    for (let i = 0; i < 1; i++)
    console.log("for_statement");
    for (let _ of [true])
    console.log("for_in_statement");
    while (x-- > 0)
    console.log("while_statement");
    do
    console.log("do_statement");
    while (false)
    };

Afterwards, you should see none of the statement bodies were indented.
